Adaptive search area for fast motion estimation
In this paper a new method for determining the search area for motion estimation algorithm based on block matching is suggested. In the proposed method the search area is adaptively found for each block of a frame. This search area is similar to that of the full search (FS) algorithm but smaller for most blocks of a frame. Therefore, the proposed algorithm is analogous to FS in terms of reg...
متن کاملEnhanced predictive zonal search for single and multiple frame motion estimation
Motion Estimation (ME) for video coding has taken an entirely different direction with the emergence of zonal algorithms. These algorithms made it possible to significantly reduce, if not almost eliminate, the tremendous computational overhead of motion estimation that was incurred in a video encoding system, while having little if any loss in quality. In this paper we further improve on these ...
متن کاملMulti-Frame Estimation of Planar Motion
ÐTraditional plane alignment techniques are typically performed between pairs of frames. In this paper, we present a method for extending existing two-frame planar motion estimation techniques into a simultaneous multi-frame estimation, by exploiting multi-frame subspace constraints of planar surfaces. The paper has three main contributions: 1) we show that when the camera calibration does not ...
متن کاملAn Efficient Search Algorithm for Motion Estimation
An efficient search algorithm using the principle of Hexagon-Based Search algorithm (HEXBS) for motion estimation called Hexagon-Based Fast Search algorithm (HEXFS) is proposed in this paper. The proposed algorithm combines the hexagon search algorithm and a two-step search algorithm which uses cross search patterns to reduce the huge calculation complexity. The experimental results show that t...
متن کاملtight frame approximation for multi-frames and super-frames
در این پایان نامه یک مولد برای چند قاب یا ابر قاب تولید شده تحت عمل نمایش یکانی تصویر برای گروه های شمارش پذیر گسسته بررسی خواهد شد. مثال هایی از این قاب ها چند قاب های گابور، ابرقاب های گابور و قاب هایی برای زیرفضاهای انتقال پایاست. نشان می دهیم که مولد چند قاب تنک نرمال شده (ابرقاب) یکتا وجود دارد به طوری که مینیمم فاصله را از ان دارد. همچنین مسایل مشابه برای قاب های دوگان مطرح شده و برخی ...
